Bernie,

I also read this attack can exploit *many* types of graphics files.  
Did the report you read say JPG files are the "preferred" target?  
I wonder what the "safest" graphics formats will be?

Some related links are included in my previous post:

Do you have a link or reference to the report you are referring to?
